Biologists study trade-offs of microscopic predators https://phys.org/news/2024-05-biologists-offs-microscopic-predators.html

Costs of being a diet generalist for the #protist predator #Dictyostelium discoideum https://www.pnas.org/doi/10.1073/pnas.2313203121

"The #amoebae prey on a very diverse group of #bacteria. But when they switch from one bacteria to another, there's a physiological cost."

PIPkinA helps amoebas maintain social distancing

Do you find slime molds repulsive? It's ok, Dictyostelium discoideum cells can sometimes find their own neighbors pretty repulsive, too. Richard Gomer and colleagues show that PIPkinA is required for chemorepulsion in Dictyostelium away from AprA, which stimulates cell movement away from dense colony centers. #amoebae #SlimeMolds #CellBiology

Paper: Yellow #polyketide pigment suppresses premature #hatching in social amoeba https://www.pnas.org/doi/10.1073/pnas.2116122119

The #multicellular stage of the #amoeba #Dicyostelium discoideum is partially regulated by an intensely yellow natural substance. The newly identified natural product of the polyketide family prevents the #amoebae #spores from hatching too early.
